How sulphide ores are extracted?

Table of Contents

Sulphide oresSulphide oresThe most common sulfide ore minerals are pyrite, pyrrhotite, chalcopyrite, sphalerite, and galena, whereas the most common oxide ore minerals are hematite, magnetite, ilmenite, and chromite.https://www.sciencedirect.com › topics › chemistry › sulfide-oreSulfide Ore – an overview | ScienceDirect Topics are a major source of Cu, Ni and precious metals. A basic principle of the extraction processes is to blow air into the molten sulphide in order to oxidise (1) S, which forms a gas and (2) Fe, which forms predominantly FeO and then partitions to a slag phase which covers the matte.

Which method is used for extraction of metal from sulphide ores?

Electrolysis is used in the extraction of metals from their ores.

Which sulphide ore is extracted by chemical leaching?

argentite

So, argentite is the sulphide where silver can be extracted through a chemical leaching process. Additional information: Froth Floatation Process: This process is the best appropriate method for sulphide ores.

What are the 3 types of methods for extracting ore?

There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal.

Which ore is sulphide ore?

The most common sulfide ore minerals are pyrite, pyrrhotite, chalcopyrite, sphalerite, and galena, whereas the most common oxide ore minerals are hematite, magnetite, ilmenite, and chromite.

What are sulfide ores?

Sulfide minerals are the source of various precious metals, most notably gold, silver, and platinum. They also are the ore minerals of most metals used by industry, as for example antimony, bismuth, copper, lead, nickel, and zinc.

What are the methods of extraction?

Extraction methods include solvent extractionsolvent extractionExtraction in chemistry is a separation process consisting of the separation of a substance from a matrix. Common examples include liquid-liquid extraction, and solid phase extraction. The distribution of a solute between two phases is an equilibrium condition described by partition theory.https://en.wikipedia.org › wiki › Extraction_(chemistry)Extraction (chemistry) – Wikipedia, distillation method, pressing and sublimation according to the extraction principle. Solvent extraction is the most widely used method.

What is the process of extracting metal from ore called?

The process of extracting metal ores buried deep underground is called mining.

How do we separate two sulphide ores by froth floatation method?

For the separation of two sulphide ores, the proportion in which oil and water are taken should be adjusted. This can also be done by using depressants such as NaCN. If an ore contains ZnS and PbS, then NaCN is added during the process.

What are the two methods of extracting metal from ore?

The methods for extracting metals from their ores are:

roasting a metal sulphide.
chemical reduction of a metal oxide.
electrolysis,

What are the 4 types of surface mining?

These mining categories are: strip mining, open-pit miningopen-pit miningOpen-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow.https://en.wikipedia.org › wiki › Open-pit_miningOpen-pit mining – Wikipedia, mountaintop removal, dredging and high wall mining.

What is sulfide ore used for?

How many are sulphide ores?

<br> Azurite, chalcoite,iron pyrites,limonite.

What are examples of sulfides?

Significant examples include: argentite (silver sulfide), cinnabar (mercury sulfide), galena (lead sulfide), molybdenite (molybdenum sulfide), pentlandite (nickel sulfide), realgar (arsenic sulfide), and stibnite (antimony), sphalerite (zinc sulfide), and pyrite (iron disulfide), and chalcopyrite (iron-copper sulfide).

What is the principle of extraction?

The principle behind solvent extractionsolvent extractionExtraction in chemistry is a separation process consisting of the separation of a substance from a matrix. Common examples include liquid-liquid extraction, and solid phase extraction. The distribution of a solute between two phases is an equilibrium condition described by partition theory.https://en.wikipedia.org › wiki › Extraction_(chemistry)Extraction (chemistry) – Wikipedia is extremely basic. The goal is to use a liquid (solvent) to dissolve (solvate) a target molecule or group of compounds (solute) and to wash them out of the solid plant material. The solvent is then separated from the solute in order to concentrate the solute.

Which solvent is best for extraction?

A good extraction efficiency was also found with methanol as extraction solventextraction solventExtraction in chemistry is a separation process consisting of the separation of a substance from a matrix. Common examples include liquid-liquid extraction, and solid phase extraction. The distribution of a solute between two phases is an equilibrium condition described by partition theory.https://en.wikipedia.org › wiki › Extraction_(chemistry)Extraction (chemistry) – Wikipedia (p < 0.05) for both solid-liquid (7.9%) and ultrasound (5.7%) methods. In a study performed by Jerman et al. [42], methanol was considered the best solvent to extract phenols using the ultrasound method.

What are the steps involved in extraction of ore?

Concentration of the or ORE DRESSING or ENRICHMENT OF THE ORE(gangue- to remove the earthly impurities) Converting into oxides by roasting(sulphide ores in presence of o2and calcination of the carbonate ores in limited amount of o2) Reduction of metaloxides into metals. Refining with the help of ELECTROLYTIC REFINING.

What are the common methods of extraction of metals?

Solution : Metals are commonly extracted by reduction with carbon.

Why only oxide and sulphide minerals are used for extraction of metals?

It is easier to obtain a metal from its oxide than from its sulphides or carbonates. Hence, in the process of extraction of metal from metal sulphides and carbonates, they are first converted to metal oxides.

What is the best type of mining?

Surface mining is best suited to extract minerals that are close to the surface of the earth. It is also usually a more cost-effective mining method compared to underground mining. Common minerals extracted using surface mining are some of the most mined including coal, iron and bauxite.

What are 5 types of mining?

There are 5 main types of surface mining, which are used in various degrees and for different resources. These mining categories are: strip mining, open-pit miningopen-pit miningOpen-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow.https://en.wikipedia.org › wiki › Open-pit_miningOpen-pit mining – Wikipedia, mountaintop removal, dredging and high wall mining.

Why are sulfides good ore minerals?

Above all, the sulfides are the most important group of ore minerals because they are responsible for the concentration of a wide range of metals as mineable deposits. They are also potential sources of pollution, be it of the air, surface waters, or soils.

How are sulphide ores concentrated?

Sulphide ores are concentrated by froth flotation process.

What is the example of sulphide ore?

What is the use of sulfides?

General Suggested Uses for Sulfides
Rare earth sulfides are semi-conductors and have been used in thermoelectric devices. Alkaline earth sulfides plus those of calcium and zinc are used for phosphor compositions. Molybdenum and tungsten sulfides are widely used, non-graphitic commercial lubricants.
